Connector for coaxial cable

Abstract

A connector ensuring good mechanical and electrical connection to a coaxial cable includes a metal housing; an insulating element mounted in the metal housing and having a split end portion; a connecting terminal inserted in the split end portion of the insulating element to thereby associate therewith, and having a split end portion for receiving and electrically connecting to a center conductor of a coaxial cable; and a fixing element attached to an outer side of the metal housing, and having a first pair of wings inward bent to compress against the split end portion of the insulating element for the same to apply a force against the split end portion of the connecting terminal, so that the center conductor of the coaxial cable is firmly held to the connecting terminal without the risk of loosening therefrom.

1. A connector for coaxial cable, the coaxial cable including a center conductor, an insulating spacer surrounding the center conductor, at least one cylindrical conducting screen surrounding the insulating spacer, and an outer sheath surrounding the cylindrical conducting screen; the connector being configured to ensure good mechanical and electrical connection to the coaxial cable, and comprising:
 a metal housing internally defining an axial guide way, and having a predetermined portion in the form of a curved connecting plate; 
 an insulating element mounted in the axial guide way of the metal housing and having a first and a second end, the second end having an axially extended slit to thereby form a split end portion; 
 a connecting terminal inserted in the split end portion of the insulating element to associate with the insulating element; the connecting terminal having a rear end with an axially extended slit to thereby form a split end portion, into which the center conductor of the coaxial cable is inserted to electrically connect to the connecting terminal; and 
 a fixing element attached to an outside of the metal housing, and including a main body with at least a first pair of wings formed thereon to locate at an outer side of the curved connecting plate of the metal housing; 
 whereby when the first pair of wings is inward bent to compress against a portion of the insulating element exposed from the curved connecting plate of the metal housing, the compressed portion of the insulating element applies a force to press against the split end portion of the connecting terminal, so that the center conductor of the coaxial cable is firmly clamped and held in the split end portion of the connecting terminal without the risk of loosening or separating from the connector. 
 
   
   
     2. The connector for coaxial cable as claimed in  claim 1 , wherein the main body of the fixing element is further provided at predetermined positions with a second, a third, and a fourth pair of wings. 
   
   
     3. The connector for coaxial cable as claimed in  claim 2 , wherein the metal housing includes a front and a rear stop plate, and the curved connecting plate being located between the front and the rear stop plate. 
   
   
     4. The connector for coaxial cable as claimed in  claim 3 , wherein the front stop plate of the metal housing has a circular flange forward extended therefrom; and the second pair of wings being bent inward to directly press against an outer surface of the circular flange, so that the fixing element is associated with the metal housing. 
   
   
     5. The connector for coaxial cable as claimed in  claim 2 , wherein the third pair of wings is bent inward to directly press against an outer surface of the cylindrical conducting screen of the coaxial cable to thereby form a grounding contact. 
   
   
     6. The connector for coaxial cable as claimed in  claim 2 , wherein the fourth pair of wings is bent inward to directly press against the outer sheath of the coaxial cable to thereby provide the coaxial cable with an increased pull-out resistance. 
   
   
     7. The connector for coaxial cable as claimed in  claim 1 , wherein the split end portion of the insulating element includes a shorter half and a longer half, and the first pair of wings of the fixing element is inward bent to compress an other surface of the shorter half, causing the shorter half to apply a force against the connecting terminal.
